- 试题详情及答案解析
- 阅读下面材料，从每题所给的三个选项（A、B和C）中，选出最佳选项。
In the months of December and January, China experienced some of the worst air pollution in its history. At times, Beijing’s Air Quality Index(AQI)was measured at 406. Any AQI reading over 150 is considered “unhealthy” and any reading over 300 is considered “hazardous.” In Shanghai, we had several days when the AQI neared 300. The PM2.5 readings were also high. PM2.5 refers to particulate (微粒的)matter smaller than 2.5 microns(微米) in diameter. These particles are small enough to get into the lungs and can cause cancer and other lung diseases.
China is now becoming acutely aware that the rush to development has come at a price and may be endangering the health of its citizens. This is something other countries have faced before. The U.K. used to be the most polluted country in the world. It wasn’t until London’s Big Smog of 1952 that people realized that air pollution was a real health hazard. Twelve thousand deaths were directly related to that “pea-souper(浓雾)” and it resulted in Parliament(英国议会)passing the Clean Air Act(《清洁空气法案》)of 1956.
China will no doubt pass similar laws. It’s a choice between wealth and health. As Beijingers and Shanghainese coughed their way through December and January, the choice may have become easier to make.

【小题5】C - 试题分析：这篇短文主要介绍了在十二月和一月的几个月里，中国经历了历史上最严重的空气污染。有时，北京的空气质量指数（AQI）测量是406。在上海，有几天接近300。任何超过150的读数被认为是“不健康”，读过300则被认为是“危险的”。中国现在越来越意识到急于发展代价是危害市民的健康。这是其他国家以前所面临的中国也将通过法律来保护环境。
【小题1】细节理解题。根据短文Any AQI reading over 150 is considered “unhealthy” and any reading over 300 is considered “hazardous.”，可知AQI读数超过150是不健康的。因为广州小于159，故选B。
【小题2】细节理解题。根据Twelve thousand deaths were directly related to that “pea-souper(浓雾)” and it resulted in Parliament(英国议会)passing the Clean Air Act(《清洁空气法案》)of 1956. 可知是因为十二万人的死亡和浓雾有关，是英国议会通过了清洁空气法案。故选A。
【小题3】细节理解题。PM2.5 refers to particulate (微粒的)matter smaller than 2.5 microns(微米) in diameter. These particles are small enough to get into the lungs and can cause cancer and other lung diseases.可知PM2.5可能会导致癌症或肺部疾病，故选B。
【小题4】词义猜测题。根据第四段根据Any AQI reading over 150 is considered “unhealthy” and any reading over 300 is considered “hazardous.”可知AQI读数超过150是不健康的那么超过300则是危险的，故选B。
【小题5】归纳理解题。根据最后一段可知人们认识到了空气污染是健康的危害。所以人们会在健康和财富中作出正确的选择，故选C。
